IPC: F01M1/06
Filed: 2002-02-21
Abstract: <P>PROBLEM TO BE SOLVED: To form a low-cost lubricant supply system permitting positive adjustment of an amount of lubricant supplied.  <P>SOLUTION: A rocker shaft 15 is provided therein with an in-shaft oil passageway 16 and a branch passageway 17 in fluid communication therewith. An oil amount adjustment path 18 is provided throughout an entire periphery of an outer peripheral surface of the rocker shaft 15. The path 18 is cut in a groove shape so as to pass across the branch passageway 17. An in-arm oil passageway 25 is provided inside a rocker arm 20, extending from an inner peripheral surface of a shaft fitting hole 26 to a sliding surface 21. The in-arm oil passageway 25 is in fluid communication with the oil amount adjustment path 18 at all times. The oil amount, adjustment path 18 is narrower than the diameter of the branch passageway 17 and that of in-arm oil passageway 25. This allows the amount of lubricant supplied to be adjusted. Further, the oil amount adjustment path 18 is provided throughout the entire periphery of the rocker shaft 15 so that the branch passageway 17, the oil amount adjustment path 18, and the in-arm oil passageway 25 are not required to achieve a stringent positional accuracy. It is therefore possible to form a low-cost lubricant supply system permitting positive adjustment of the amount of lubricant supplied.  <P>COPYRIGHT: (C)2003,JPO
